The standing root token this doc described is retired. Replaced the
2-flow table with the real 3-flow model now in place: routine AppRole
auth, a narrowly-scoped provisioner AppRole for occasional bootstrap
work, and a break-glass generate-root path for the rare cases the
provisioner deliberately can't cover. Alerting row corrected to note
the audit-log check fires on any root-policy token generically, not
a specific standing one.
